Eep! the lunatics are running the asylum! Run away!

In fairness, Igor and I just work here.
I'd be interested in seeing Aquacoat on bare timber (like a traditional grain filler) sanded flat then stained. Aquacoat says it can be done that way.
A similar process can be done with shellac as well. (The slurry method I regularly bang on about)
Good effort with the testing too. Keeping track of what's what can do your head in! (at least my head anyway!)
Thanks for reporting.

Make sure that's Aquacoat the filler and not Aquacote the top coat
Timbermate slurry seems to be the one I come across the most.
I had a test board like that from an early test, but don't know what I did with it. If I can find it I'll post it.
Probably also worth noting that the dyestain I am using is not exactly like powder dye. It has a little bit of binding agent in it. The added top coat should help it adhere. That said, looking at them in the sunlight this morning I decided I would probably use a coat of shellac in an abundance of caution.

Here's what it looks like when yo use AquaCoat first, then stain:
Comparing it to the prior attempt: Upper left--stain then AquaCoat, upper right--stain then shellac then AquaCoat, bottom--AquaCoat then stain. All three have three coats of stain (although the manufacturer recommends just one or two).
It's clear that the stain-first is darker. In the pics it looks like the AquaCoat-first board is just stained lighter. In reality it looks mottled. I tried to capture this with a closeup with mixed results...
In real life it looks like there are places where the stain did not really penetrate at all, and other places where it penetrated deeply. This is not necessarily bad, if what you are going for is road worn.
I did not take a pic of my original test, but I did that with AquaCoat first the pure General Finishes Dye Stain (no 10% top coat added). What I remember is that the results were similar, and maybe a tad worse. It could be that the added top coat helped the dye stick to the mottled places so it was not quite as bad. Or it could be that I don't remember perfectly.
I don't have the materials to test this, but I suspect that the AquaCoat-first approach would work fine with a commercial stain or with a gel stain. I don't think I would recommend using it with a deep-penetrating water based dye stain though.
Added a coat of shellac on top of the stain. Next stop, pore filling with Aqua Coat.

Thanks for the info in your previous post. I appreciate your effort into the research. Beneficial to all.
Doesn't look like it quite lives up to the manufacturer's option of pre-stain application.

Not with dye stain, anyway. The stain MFG and users on the internet have mostly suggested using it Aqua Coat over not under.
Here's a vid from the Aqua Coat people. They're also using the same kind of dye stain that I used.
